Abstract (en)

[origin: WO0019241A1] A system and method of processing seismic signals wherein seismic data resulting from a reflected seismic wave is received at a multi-component receiver (300). A mask trace (305) is generated as a function of the seismic data received at the multi-component receiver, and a single type of seismic signals from the seismic data received at the multi-component receiver is identified and extracted utilizing the mask trace. Extracting the single type of seismic signals (310) includes multiplying the seismic data received at one component (340) of the multi-component receiver with the mask trace wherein the single type of seismic signals represents seismic waves received at the one component of the multi-component receiver.
